Question

write a quadratic function with zeros -1 and 3. write your answer using the variable x and in standard form with a leading coefficient of 1. g(x) =

Explanation:

Step1: Use zero factor form

$g(x)=(x - (-1))(x - 3)=(x+1)(x-3)$

Step2: Expand the binomials

$g(x)=x\cdot x - 3x + 1\cdot x - 1\cdot3$

Step3: Simplify to standard form

$g(x)=x^2 - 2x - 3$

Answer:

$g(x)=x^2 - 2x - 3$
